[0021] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments:

[0022] Such as Figures 1-5As shown in the figure, the utility model provides a high-purity nitrogen production device with a voltage equalizing structure, including a first adsorption tower 1, a second adsorption tower 2 and a controller 10. Installation mechanisms 9 are arranged at one ends of the first adsorption tower 1 and the second adsorption tower 2. The installation mechanism 9 includes an installation shell 913, a screw 901, a clamping plate 902, a protection plate 904, a pressing rod 907 and a compression spring 909. A number of switches 104 are arranged on one side of the controller 10, and an installation frame 101 is fixedly installed on the outer wall. The installation frame 101 fits with the inner wall of the installation shell 913. The screw 901 protects the controller 10 through the clamping plate 902 and the protection plate 904. When the controller 10 needs to be taken out, rotating the screw 901 can release the limit on the protection plate 904 and the controller 10, making it convenient to take out. When the controller 10 needs to be started or closed, by pressing the pressing rod 907, the pressing rod 907 can press the switch 104 after being pressed, and reset through the compression spring 909, achieving the effect of repeated use.

[0023] When the controller 10 needs to be replaced or repaired, the staff rotates the screw 901 clockwise. When the screw 901 rotates, it can drive the clamping plate 902 to move vertically when rotating. When the screw 901 rotates by a certain amplitude, the rotation direction and moving height of the clamping plate 902 will no longer block the connecting plate 903. At this time, the staff can pull up the connecting plate 903, so that the connecting plate 903 drives the protection plate 904 to move, and then no longer protects the controller 10. Then the controller 10 can be taken out. The operation is simple. When the controller 10 is installed, the above steps can be reversed to quickly install the controller 10 in the installation shell 913 and protect it. While improving the installation and removal efficiency, it can also fully protect the controller 10, extend the service life of the controller 10, and improve the applicability.

[0024] After the controller 10 is installed, the staff presses the pressing rod 907. After the pressing rod 907 is pressed, it can compress the compression spring 909. When the pressing rod 907 presses the switch 104, the staff no longer applies force to the pressing rod 907. At this time, the compression spring 909 releases pressure, and the controller 10 can be started or closed without taking out the controller 10. At the same time, after the operation, the pressing rod 907 can automatically reset, which is convenient for the staff to operate next time. There is no need to take out the controller 10, reducing the probability of damage, further simplifying the structure, and improving the applicability.

[0025] In one embodiment, the installation mechanism 9 further includes a connecting plate 903, a notch 912, a protective plate 904, an installation screw rod 905 and a threaded hole 906. The two installation screw rods 905 are respectively threadedly connected to the first adsorption tower 1 and the second adsorption tower 2, and the other ends are fixedly connected to the installation housing 913. The notch 912 and the threaded hole 906 are both opened at the top of the installation housing 913. The screw rod 901 is in threaded cooperation with the threaded hole 906. The clamping plate 902 is fixedly sleeved on the screw rod 901. The protective plate 904 is fixedly connected to the bottom of the connecting plate 903. The transparent window 914 is fixedly installed on the inner wall of the protective plate 904. The connecting plate 903 fits against the top of the installation housing 913. The protective plate 904 is in sliding cooperation with the notch 912. When the screw rod 901 rotates by a certain amplitude, the clamping plate 902 can cooperate with the installation housing 913 and squeeze the connecting plate 903.

[0026] When the screw rod 901 rotates, it is in threaded cooperation with the threaded hole 906. At this time, the screw rod 901 can move its own height when rotating. When the screw rod 901 moves, it can drive the clamping plate 902 to move. At this time, the clamping plate 902 can also move vertically when rotating. When the screw rod 901 rotates by a certain amplitude, the orientation and the moving height of the clamping plate 902 will no longer block the connecting plate 903. At this time, the staff can pull up the connecting plate 903, so that the connecting plate 903 drives the protective plate 904 to move, and then no longer protects the controller 10. The disassembly method is simple, and it does not require the staff to spend a lot of disassembly time, simplifies the operation difficulty, and improves the applicability and work efficiency.

[0027] In one embodiment, the installation mechanism 9 further includes a socket circular plate 908, a sliding groove 910 and a limiting groove 911. A plurality of sliding grooves 910 are all opened at one end of the installation housing 913. The limiting groove 911 is opened inside the sliding groove 910. The extrusion rod 907 is in sliding cooperation with the sliding groove 910. The socket circular plate 908 is fixedly sleeved on the extrusion rod 907 and is in sliding cooperation with the limiting groove 911. The two ends of the compression spring 909 are respectively connected to the limiting groove 911 and the socket circular plate 908.

[0028] After the extrusion rod 907 presses the switch 104, the staff no longer applies a force to the extrusion rod 907. At this time, the compression spring 909 releases pressure, that is, the controller 10 can be started or closed without taking out the controller 10. At the same time, after the operation, the extrusion rod 907 can automatically reset, which is convenient for the staff to operate next time and further improves the applicability.

[0029] In one embodiment, a first ventilation pipe 110 and a second ventilation pipe 210 are respectively fixedly installed at the tops of the first adsorption tower 1 and the second adsorption tower 2. One ends of the first ventilation pipe 110 and the second ventilation pipe 210 are both provided with pneumatic valves 7, and a connecting pipe 6 is fixedly connected between the two. An external connecting pipe 11 and a plurality of fixing rods 8 are fixedly installed between the first adsorption tower 1 and the second adsorption tower 2.

[0030] When it is necessary to transfer the gas in the first adsorption tower 1 to the second adsorption tower 2, open the pneumatic valve 7 at the top of the first adsorption tower 1, and the gas can be transferred through the connecting pipe 6;

[0031] The transfer method is common knowledge and will not be explained here.

[0032] In one embodiment, protective baffles 5 are fixedly installed outside the first adsorption tower 1 and the second adsorption tower 2, and a number of legs 401 are fixedly installed at the bottom. The bottom of the legs 401 is fixedly installed with a mounting seat 402, and the bottom of the mounting seat 402 is fixedly connected to a support base 3. One end of the support base 3 is fixedly installed with an external base 12, and a number of mounting holes 301 are provided on the outer wall.

[0033] Connected through a number of legs 401, mounting seats 402 and support bases 3, the first adsorption tower 1 and the second adsorption tower 2 are connected to improve the structural stability. The external base 12 is used to install external equipment to improve applicability.

[0034] In one embodiment, a number of display screens 102 and buttons 103 are provided on one side of the controller 10.

[0035] The display screens 102 and buttons 103 are both existing technologies and will not be explained here.

[0036] The working principle of the portable nitrogen production equipment will be specifically described below:

[0037] When it is necessary to replace or repair the controller 10, the staff rotates the screw 901 forward. When the screw 901 rotates, it is in threaded cooperation with the screw hole 906. At this time, the screw 901 can move its own height when rotating. When the screw 901 moves, it can drive the clamping plate 902 to move. At this time, the clamping plate 902 can also move vertically when rotating. When the screw 901 rotates a certain amplitude, the orientation and height of the clamping plate 902 rotating will no longer block the connecting plate 903. At this time, the staff can pull up the connecting plate 903, so that the connecting plate 903 drives the protective plate 904 to move, and then no longer protects the controller 10. Then the controller 10 can be taken out. The operation is simple. When the controller 10 is installed, the above steps can be reversed to quickly install the controller 10 in the installation housing 913 and protect it. While improving the installation and removal efficiency, it can also fully protect the controller 10, extend the service life of the controller 10, and improve applicability;

[0038] After the controller 10 is installed, the staff presses the extrusion rod 907. After the extrusion rod 907 is pressed, it can slide in the chute 910 and drive the socket circular plate 908 to move. At this time, the socket circular plate 908 is in sliding fit with the limit groove 911 and compresses the compression spring 909 under the action of the limit groove 911. When the extrusion rod 907 presses the switch 104, the staff no longer applies force to the extrusion rod 907. At this time, the compression spring 909 releases pressure, that is, the controller 10 can be started or stopped without taking out the controller 10. At the same time, after the operation, the extrusion rod 907 can automatically reset, which is convenient for the staff to operate next time and further improves the applicability.

[0039] The above has generally described the present utility model in detail. However, based on the present utility model, some modifications or improvements can be made, which are obvious to those of ordinary skill in the art. Therefore, the modifications or improvements made without departing from the spirit of the present utility model are within the protection scope of the present utility model.
